oh they’re digital,

but they’re still negatives as far as I’m concerned. Let’s just say that they definitely look like they need a lot of work when they come fresh off the camera. Shooting in raw will do that, so I hear. Color and white balance — two especially important components of photographing mushrooms — has frustrated me more than anything with digital photography. And while it’s no solultion in and of itself, digital raw at least offers the versatility that jpegs are too static to provide.

Much of what I’ve submitted here so far was taken on a nikon coolpix L3, bought in Bolivia for at least 3 times its market value in the US. The ecuador shots are from my current camera, a nikon d60, but were almost all shot in jpeg. The Bolivia & Panama shots to follow (plus a few more from Ecuador) are from the same camera but all raw, with a little more liberal use of the tripod which I’ve found to be absolutely indispensible for this work. I aim to get my hands on a D90 before the year is out.

“To-be-developed”? Someone’s still living in the 20th century. :)

I think you’re right, or at least on the right track. Striking similarity between the two, no doubt. Nice find. The Guyana stuff is fascinating as well. Is there somewhere where more pics can be found?

By the way, expect more oddballs from the polyporaceae/hymenochaetaceae as specimens from this past year’s Bolivia survey and some to-be-developed Ecuadorian photos from last summer slowly make their way here.

Dr. Cathie Aime gave a lecture at our MOMS winter banquet this year. She showed many photos of new species they had discovered in Guyana. This one looks like a dead ringer for yours — see: http://news.mongabay.com/2008/0721-hance_fungi.html
about halfway down for the photo.

that poroid surface is mindblowing! You might want to have it as your thumbnail…

there are many filoboletus in this region of the world, but they are (almost) always characterized by a smooth hymenium composed of pores too small to be seen with the naked eye. Stipes are always centrally located, and fruiting bodies can be resilient and leathery (esp. the pelicule and esp. when dry, see http://www.flickr.com/photos/myxomop/2697926526) but are usually fleshy and never woody. This, to me, resembles a tiny Amauroderma much more than it does a Filoboletus, or one of those crazy genera formerly lumped into Polyporus.

Here’s the reference I used for a possibility:
